how to batch panorama 2 similar named images

[Msync]

Hi,
thought i make it easy on myself by changing the filenames of pan images similar, but i do not know what the command line argument for panorama is and couldn't find it in the documentation.

i now have 2 folders l and r containing files IMG_0001.jpg, IMG_0002.jpg etc and i would like to stitch same named files together.
where the images in the 'l' folder should be the left one and the images in the 'r' folder should end up at the right.

i tried copy/paste with the advanced editor, but that just created a new image where the second one was on top of the first, if i want with transperancy. but that was not what i wanted.

i also tried pano.vbs, but couldn't get that working,

then i thought, should i create a empty file first with double width and then copy/paste both images in the new image file?

any suggestion is appreciated.
thanks

/panorama=(X,files)

- create panorama image from input files; X = direction (1 or 2)

from help/Command Line Options
Example for /panorama:

Syntax: /panorama=(X,file1,...,fileN)
First parameter (X) is the direction: 1 = horizontal, 2 = vertical, wildcards for file1-N are allowed.
i_view32.exe /panorama=(1,c:\test1.bmp,c:\dummy.jpg)
Create horizontal panorama image from 2 other files.
i_view32.exe /panorama=(1,c:\test.tif,c:\*.bmp)
i_view32.exe /panorama=(2,c:\test.tif,c:\*.bmp,c:\dummy.jpg,c:\1 23*.gif)
i_view32.exe /panorama=(2,c:\test.tif,"c:\crazy, comma filename.jpg")
i_view32.exe /panorama=(2,filelist=c:\mypics.txt)
